Summary: This article introduces a laboratory course on food chemistry designed for nonmajors, which can be delivered in either a traditional or fully remote, asynchronous format. The course aims to help students develop an understanding of how chemists view the world and generate knowledge. By using food as a medium for scientific exploration, the course connects to students' lives and has been well-received by students in summer terms from 2019 to 2021. Instead of focusing on content, the course emphasizes learning the scientific method, allowing assessments to evaluate students' understanding of posing and testing hypotheses, identifying sources of error, determining uncertainty, analyzing results, etc.

Summary: The use of interlocking toy building blocks (such as Lego) as teaching modules for chemistry allows for a hands-on and visual approach to understanding various chemical concepts. These modules were demonstrated in undergraduate introductory and general chemistry classrooms, using an online mode of delivery for better accessibility.

Summary: This article introduces a program that introduces high school students in Melbourne, Australia to X-ray crystallography in the context of chemistry research. The program allows students to conduct original experiments, perform reactions, and attempt to grow crystals of reaction products. The success of the program is evident from student feedback and scientific outcomes, with previously unknown compounds synthesized and their structures determined. The program has also resulted in the publication of two reports with students listed as coauthors, making it of interest to science educators designing outreach activities for high school students.

Summary: Metal-organic frameworks (MOFs) are highly crystalline porous materials with customizable structures. In this experiment, undergraduate students synthesize two isostructural zirconium-based MOFs, UiO-66 and UiO-67, and characterize them using powder X-ray diffraction (PXRD). The MOFs can be further characterized through various techniques such as nitrogen adsorption analysis, infrared spectroscopy, thermogravimetric analysis, nuclear magnetic resonance spectroscopy, and scanning electron microscopy. By analyzing and describing their results, students develop practical laboratory skills and expand their knowledge in inorganic chemistry, materials chemistry, MOFs, crystallography, and other characterization techniques.

Summary: This undergraduate laboratory experiment introduces the synthesis of biologically significant bis-4-hydroxycoumarins using a new catalyst. The main learning outcomes include experimental setup plan, monitoring the reaction by TLC, isolation of the product, safe laboratory handling procedures, and the significance of data reproducibility of the result. The products are characterized by various analytical techniques such as melting point, NMR, DEPT NMR, and FTIR spectra. This cost-effective experiment with wide substrate applicability also introduces the concept of research work on multicomponent condensation reaction among the students.

Summary: The COVID-19 pandemic in Thailand led to a shift to online learning, but this posed a challenge for laboratory courses. To address this, the Department of Chemistry at Chulalongkorn University revised four in-class experiments to be conducted in a Lab@Home format, and included additional activities and opportunities for students to design their own experiments.

Summary: This study investigates sources and impacts of anxiety in online chemistry learning. Perceived ease of use is negatively correlated with chemistry anxiety, but positively correlated with math, computer, and trait anxiety. Math and trait anxiety do not directly influence perceived ease of use.

Summary: Surface stress is rarely discussed in chemistry, but it is closely related to size-dependent lattice changes in nanocrystals. Different materials exhibit different surface stress behaviors with changes in crystal size, with some materials showing tensile surface stress and others showing compressive surface stress. The coordination of surface atoms and lattice-matching between surface and interior play key roles in determining surface stress in nanostructures.

Summary: Recent developments indicate that the heat capacity of nano-oxides is dependent on their size, as the product of bulk modulus and thermal expansion coefficient scales with isometric heat capacity. The size dependence of heat capacity is explored by examining the product of bulk modulus, thermal expansion coefficient, and lattice parameter, which shows maxima at certain crystal sizes and decreases with decreasing size. This contradicts the heat capacities of metals, which are larger in nano-grains, and may be explained by the absence of electronic carriers in oxides.
